Supporting Files

Let's start populating this with all of the files that I know I've needed to support [my calendar-ics implementation](https://github.com/smtech/canvas/tree/dev-calendar-ics) in the past, including licenses and read me files.

Of particular note: to use phpicalendar, I need to be sure that this project is also GPLv2. And so, it is.
